Thank you Ms D you are a blessing and I appreciate your help and knowledge. I see my neurologist in a month to undergo further testing. I think I may have had a transient ischmeic attack from my cocaine binge. The nerves in the left side of my toes don't feel really tight and the tingling is mild so maybe I could be healing (or maybe not). I'm 28yrs old and I'm clean of all drugs since my relapse and hope to start truck driving school if all goes well with my toes/leg. Is it better to take b12 sublingual or regularly???
